![]() Where could be the lesionThe pupil is a crucial part of our visual sy. ![]() Conveniently, a popular mnemonic to remember Argyll Robertson pupils is that, just like prostitutes, they "accommodate but do not react". The pupil constricts during accommodation reaction but does not respond to torchlight. The Argyll Robertson pupil occurs when a disease interferes with the light reflex pathway, thereby inhibiting the pupil’s natural response to bright light. Named after Douglas Argyll Robertson (1837–1909), a Scottish surgeon and ophthalmologist, who first described this condition in mid-1860s in patients with neurosyphilis.Īrgyll Robertson pupils are also sometimes called "prostitute's pupils" because of their association with late neurosyphilis. The exact anatomical lesion behind this phenomenon is unknown but is thought to be caused by bilateral damage of the pretectal nuclei in the midbrain. Example of patient with Argyll Robertson pupil with neurosyphilis. There are a handful of pupillary abnormalities that every clinician should know. When seen in these non-syphilitic etiologies, the pupil is termed ' pseudo-Argyll Robertson pupil' 3. Argyll-Robertson Pupil: Light Near Dissociation. There is also one case report of light-near dissociation associated with malignant lymphoma ( Lapresle and Man 1979 ). It is described with neurosyphilis and peripheral neuropathies. It is a highly specific sign of late neurosyphilis, however can also occur in diabetic neuropathy, multiple sclerosis, alcoholic midbrain degeneration, and stroke 2,3. Argyll Robertson Pupil syndrome is characterized by absence of pupillary light reflex with retention of pupillary constriction to near vision ( Thompson 1987 ). youtube, Flat engine pdf search, Patha bhavan dankuni address book Sara. Argyll Robertson pupil is usually bilateral and presents as bilaterally miotic and irregular pupils, which constrict briskly with accommodation but do not react to bright light therefore displaying light-near dissociation 1.
